A light guide device having a first surface and a second surface opposite to each other is provided. The first surface includes a plurality of light guide microstructures arranged in a first direction. Cross sections of at least one part of the light guide microstructures in the first direction are non-isosceles triangles. Herein, a distribution position of the light guide microstructures whose cross sections are non-isosceles triangles are symmetrical to a central axis of the light guide device in the first direction, and a maximum base angle of the cross section of each of the light guide microstructures is away from the central axis. A display apparatus including the light guide device is also provided. Through the light guide device and the display apparatus provided by the disclosure, light emission intensity of the display apparatus at a large viewing angle is improved.
